 A hack tmux menu script to manage multiple tmux sessions
+
+---
+
+After I discovered tmux I searched for a way to manage multiple groups of tmux sessions under one unified script.  
+
+Not finding anything (or maybe just not looking well enough) I decided to write my own.
+
+It ain't pretty, but I've been using for over a year now and it's become an integral part of my workflow.  Maybe
+someone could benefit from it?  Or help me extend it?
+
+My setup works this way:
+
+Imagine you have multiple SSH connections
+
+* web-dev
+* web-prod
+* database-dev
+* database-prod
+
+... and you want to group them together in similar groups.
+
+With this script you can name collections of sessions and switch between them easily with just a few keystrokes.
+
+Let's see an example using the above connections:
+
+    case $session in
+        web)
+            if [[ $tcheck == 0 ]]; then
+                tmux new-session -d -s web
+                tmux rename-window 'local'
+                tmux new-window -t 1 -n 'root@web-dev' 'exec ssh root@web-dev.example.org'
+                tmux new-window -t:2 -n 'user@web-prod' 'exec ssh user@webprod.example.org'
+            fi
+        tmux attach-session -t web
+    ;;
+
+    case $session in
+        database)
+            if [[ $tcheck == 0 ]]; then
+                tmux new-session -d -s database
+                tmux rename-window 'local'
+                tmux new-window -t 1 -n 'root@database-dev' 'exec ssh root@databasedev.example.org'
+                tmux new-window -t:2 -n 'user@database-prod' 'exec ssh user@wdatabase.example.org'
+            fi
+        tmux attach-session -t database
+    ;;
+
+
+Calling the script with a pre-determined session name (ex: `./tmux-menu.sh web` or `tmux-menu.sh database`) first 
+checks to see if there is already a session group with that name.  If not, it creates a new group with the 
+commands you specify and names each connection in tmux.  
+
+If the session group *does* already exist, it simply switches you to that group.
+
+If you alias `tmux-menu.sh` to something shorter (like `tm`), switching between active sessions is as 
+easy as `Ctrl-A + d` (to detach) and `tm web` (to attach or create the web group).
+
+Killing session groups is as easy as `tmux-session kill -t web`.
